please recite the pom catch a little rhyme by eve merriam
Once upon a time
I caught a little rhyme
I set it on the floor
but it ran right out the door
I chased it on my bicycle
but it melted to an icicle
I scooped it up in my hat
but it turned into a cat
I caught it by the tail
but it stretched into a whale
I followed it in a boat
but it changed into a goat
When I fed it tin and paper
it became a tall skyscraper
Then it grew into a kite
and flew far out of sight...
